MPROVED BURGLAR-ALARM.

Speciication forming part of Letters Patent No. dl, dated March 13,1866.

To all whom it may concern.:

Be it known that l, MATTHEW C. HEPTIN- STALL, of' Enfield, in the county of llalitax, State ot' North Carolina, have invented new and useful Improvements in Burglar-Alarms for the Protection ot' Life and Propertyr 5 and I do hereby declare the following to be an eX- act description thereof, reference being had to the accompanying drawings, and to the letters ot reference marked thereon, making a part of this speeiication.

The nature of my invention consists in the arrrangement and combination of the gun with its spring-han1mer and the devices for operating the hammer, all inelosed in an iron box to be protected from the weather, for the purpose of having.;` the gun in readiness at the inside ot' a door or window, to prevent burglars or assassins from entering the house, or to be placed in a safe to protect the safe from being robbed-in short, to be placed in any position to protect life and property.

Figure 1 represents a top View; Fig. 2, a sectional view. Figs. 3 and 4 are perspective views of the outside of the box containing the tire-arms and the devices for tiring the gun. A

A is a cast-iron or bra-ss barrel seven inches long and one and a halt' inch in diameter, with a bore sufficiently large to carry a halt'- ounee ball, to be effective at a distance of two hundred yards, it properly aimed and elevated. Itis confined to the bottom of the box at B by means a screw, and passes through thefbox at C, which holds the gun and muzzle stationary.

D is the lnainspring or hammer, that is ot' sufficient strength to burst a niuslzet percussion-cap. lt is confined and fastened to the barrel A, near the muzzle, by means of a screw, as shown at E, and falls with sufficient force on the tube at F to produce explosion of the cap.

The extreme end G is hook -shaped, with a rounded point that rests on H, that is a small L projection from roller l, when set for operation, and is kept in that position by rod I, that is placed on the movable standard J at K, which standard is perpendicular when rod I is resting on it. ary by means oi' journals entering each side of the box.

L is the block or foundation, in which standard J is confined by means ot' a screw' at M,

and can be regulated to Work hard or easy by tigh teniug or loosening said screw.

N is a standard, to which the lever O is confined by ascrew atl. Q Q are the loop-holes in which to fasten the thread or wire in lever O.

1t is the pin attached to lever 0, which removes standard J when the thread or Wire Sis pulled, and causes the rod l to fall, throwing the niainspring oit' the point, andthe gun lires. S t5 are the threads or Wires coniined to lever 0, passing through each end of the box.

Figs. 3 and 4l are side views of the box con taining the lire. arms inelosed, showing.,r the fastening for the top at T and the hole for thread or wire at V, also the port-hole at W' and the hinge of the lid at X, with the string; or wire hole at Y.

Z is an extension of the bottom of the box, through which a screw is to be passed to conne the box, wherever desired, inside of a door or Window, or any place to protect property. There is also a rin g or handle at top for carrying the box. The box also preserves the devices from injury by the weather and secures them safely from intrusion.

What l claim as my invention, and desire to secure by Letters Patent, is-

The arrangement and construction of a gun with a mainspring,1), rod l, movable standard J, standard N ,and lever 0, when arranged, combined, operated, and tired from the inside ot the box, as herein described, and for the purposes set forth.

Roller 1 is made station-
